I've heard that it's normal for systolic blood pressure to be up during or just after running/exercise, but that diastolic should basically stay the same as when you just got out of bed in the morning.

My diastolic pressure when I've just gotten out of bed in the morning is usually in the 60s and sometimes 70s, but lately (last year-ish, I never really paid much attention before then) within 10/15 minutes after a 5 mile run my diastolic pressure is up in the low 80s, and just today it was in the low 90s which is a first.

Should I be worried?
